Hi. I have been using CCleaner free version for some years. I also use the free version of Avast. Actually, I purchased 2 copies after using the free version for some years but, reverted back to the free version after Avast kept offering me additional add-ons for an extra cost, I presume CCleaner uses the same tactics. I find this to be completely unethical - if you buy a product it should come with all the bells and whistles. You should not be drip fed to get the entire suite. I am well able to update my own software and drivers so, the free version serves me well enough but, these types of salea tactics are totally unfair for users who are not tech savvy!
